Gear treatment apparatus

Claim 2

Gear treatment apparatus for treating a gear having a shape, comprising: a. a base, b. a workhead mounted on the base and including means to support the gear and rotate it about its axis, the workhead being provided with a motor-driven first spindle on which the gear is mounted, and the workhead also including a hinge located a substantial distance from the spindle axis and at a right angle thereto, c. a wheelhead mounted on the base and including a second spindle on which is mounted an abrasive wheel and a motor for driving the second spindle, d. means associatEd with the wheelhead to press the wheel toward the gear so that the wheel follows the shape of the gear as the gear rotates.

Claim 3

Gear treatment apparatus as recited in claim 1, wherein the workhead is movable from a first position at which the first spindle is vertical to a second position at which the first spindle is horizontal.

Claim 4

Gear treatment apparatus as recited in claim 2, wherein in the second position a secondary spindle also extends horizontally, but in the opposite direction, and wherein a tail stock is slidably mounted on the base for use with the secondary spindle to mount a gear on centers.

Claim 5

Gear treatment apparatus, comprising: a. an elongated rectangular base having a generally flat horizontal upper surface having two long side edges, b. a workhead mounted at one end of the base and having a motor-driven spindle on which a gear can be mounted and rotated, c. a set of ways mounted along each long side edge of the surface of the base, d. a wheelhead slidably mounted on each set of ways and including a spindle on which an abrasive wheel is mounted, e. means associated with each wheelhead to press the wheel resiliently toward the gear, f. a secondary set of ways mounted at the other end of the base between the two previously-mentioned sets, and g. a tail stock mounted on the secondary set.

Claim 6

Gear treatment apparatus, comprising: a. an elongated rectangular base having a generally flat horizontal upper surface having two long side edges, b. a workhead mounted at one end of the base and having a motor-driven spindle on which a gear can be mounted and rotated, c. a set of ways mounted along each long side edge of the surface of the base, d. a wheelhead slidably mounted on each set of ways and including a spindle on which an abrasive wheel is mounted, e. means associated with each wheelhead to press the wheel resiliently toward the gear, f. a secondary set of ways mounted at the other end of the base between the two previously-mentioned sets, and g. a tail stock mounted on the secondary set.
